Write an expression for potential $V( \overrightarrow{r})$ at a point due to two point charges $q_1$ and $q_2$ at $\overrightarrow{r_1}$and $\overrightarrow{r_2}$ respectively.

$V(\overrightarrow r ) =\large\frac{1}{4 \pi \in_0} \frac{q_1}{\bigg |\overrightarrow{r} - \overrightarrow{r_1} \bigg|}+\frac{1}{4 \pi \in_0} \frac{q_2}{\bigg|\overrightarrow{r} - \overrightarrow{r_2}\bigg|}$
